Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As background art says, under current power supply mode, the shuttle is difficult to be long-time continuous operation, leads to the problem of storage inefficiency. The inventor researches and finds that the reason for the problem is that: when the shuttle vehicle is powered only by the super capacitor, the energy density of the super capacitor is low, and therefore, if the moving path of the shuttle vehicle is too long, the super capacitor cannot provide enough electric energy for the shuttle vehicle to support the shuttle vehicle to move to the charging device for charging. In this case, manual intervention is required to restore power to the shuttle, such as manually moving the charging device to the location of the shuttle or moving the shuttle to the location of the charging device. However, considering the hysteresis of manual handling, the efficiency of manual handling, the area of the warehouse and the concealment of the shuttle car in the warehouse, it is difficult for the staff to quickly find the electric quantity of the shuttle car is exhausted and recover the electric energy, so that the shuttle car cannot be put into use due to the exhausted electric energy for a long time, and the warehousing efficiency is reduced. When the shuttle car is powered only by the lithium battery, the performance of the lithium battery is greatly influenced by the temperature, and the charging time of the lithium battery is long, so that the shuttle car needs to spend more time on charging, the available time is short, and the storage efficiency is reduced.
In order to solve the above problem, an embodiment of the present application provides a power supply circuit and a cargo moving device, where the power supply circuit may supply power to the cargo moving device through a super capacitor module or a storage battery module therein. Specifically, the super capacitor module is preferentially used for supplying power to the cargo moving device, so that the service life of the storage battery module with long charging time can be shortened, and the charging times of the storage battery module are reduced. Because the super capacitor module possesses the fast characteristics of charging, consequently, the power supply mode of this application can reduce and provide the module because of the electric energy and charge and lead to the condition that goods mobile device can not use. Simultaneously, this application still regards as the back-up source with battery module for the goods mobile device can get back to charging apparatus department and charge under the condition that super capacitor module electric quantity exhausts, need not artifical intervention and charges. Therefore, under the power supply mode of this application, goods mobile device can have longer usable time, and then can improve storage efficiency.
In one embodiment, the present application provides a power supply circuit. As shown in fig. 1, the power supply circuit specifically includes a storage battery module 110, a super capacitor module 120, a gating module 130, and a power supply control module 140. The battery module 110 is a module capable of providing electric energy through one or more batteries, and it can be understood that the number of the batteries included in the battery module 110 and the type of each battery can be determined according to actual conditions, and when the battery module 110 includes a plurality of batteries, the interconnection relationship between the plurality of batteries can also be determined according to actual conditions, which is not limited in this application. In one embodiment, the battery module 110 may be a lithium battery module, i.e., the battery module 110 may include one or more lithium batteries. Because the lithium battery has the advantages of high energy density and high working voltage, the volume of the power supply circuit can be reduced by adopting the lithium battery to realize the storage battery module 110.
The gating module 130 refers to a device or a circuit that includes a plurality of paths and can selectively turn on one of the plurality of paths, and may be implemented based on a gating switch or a relay, for example. In one embodiment, the gating module 130 may be a relay, in which case, a coil connection terminal of the relay serves as a first terminal of the gating module 130, a normally closed terminal of the relay serves as a second terminal of the gating module 130, a normally open terminal of the relay serves as a third terminal of the gating module 130, and a common terminal of the relay serves as a fourth terminal of the gating module 130. Alternatively, the normally open end of the relay may be used as the second end of the gating module 130, the normally closed end of the relay may be used as the third end of the gating module 130, and the first end and the fourth end of the gating module 130 may be as described above.
The power supply control module 140 refers to a device or a circuit having a logic processing capability, a signal receiving function, and a signal outputting function. For example, the power control module 140 may include a controller, and further, the power control module 140 may further include a peripheral circuit corresponding to the controller. It is understood that the specific type of the controller and the specific configuration of the peripheral circuit can be determined according to practical situations, and the present application is not limited to this specific type. In one embodiment, the power supply control module 140 may be implemented by a PLC (Programmable Logic Controller), so that the power supply control module 140 may have the advantages of high reliability, strong anti-interference capability, light weight, small size, and low energy consumption.
It should be noted that the power supply control module 140 of the present application may be an additionally disposed module independent from the cargo moving device, or may be implemented by multiplexing the total control module in the cargo moving device. For example, a first PLC may be provided in the cargo moving device, and the first PLC may be used as a general control module for controlling the operation of the cargo moving device. In this case, the power supply control module 140 in the power supply circuit may be the first PLC or may be an additional second PLC. In one embodiment, the power control module 140 of the power circuit can be implemented by multiplexing the overall control module within the cargo moving device to reduce the size and cost of the power circuit.
The connection relationship of the modules in the power supply circuit can be as shown in fig. 1. Referring to fig. 1, a signal input end of the power supply control module 140 is connected to a power supply end of the super capacitor module 120, a signal output end of the power supply control module 140 is connected to a first end of the gating module 130, a second end of the gating module 130 is connected to a power supply end of the super capacitor module 120, a third end of the gating module 130 is connected to a power supply end of the storage battery module 110, and a fourth end of the gating module 130 is used for connecting to the power utilization module 210 of the cargo moving apparatus. It is understood that the power module 210 of the cargo moving device refers to a device or circuit of the cargo moving device that needs to be driven by electric energy, and includes, but is not limited to, a moving module (e.g., a power wheel moving module), a communication circuit, and the like.
The signal input terminal of the power supply control module 140 is connected to the power supply terminal of the super capacitor module 120 to obtain the remaining power of the super capacitor module 120. The power supply control module 140 may output a first gating signal to the gating module 130 to turn on a connection between the second terminal of the gating module 130 and the fourth terminal of the gating module 130 and turn off a connection between the third terminal of the gating module 130 and the fourth terminal of the gating module 130 when the remaining power of the super capacitor module 120 is greater than the preset power threshold. In this way, when the super capacitor module 120 is sufficiently charged, the super capacitor module 120 can be preferentially used to supply power to the power utilization module 210 of the cargo moving device.
When the remaining power of the super capacitor module 120 is less than the preset power threshold, the power supply control module 140 may output a second gating signal to the gating module 130 to turn on the connection between the third terminal of the gating module 130 and the fourth terminal of the gating module 130, and turn off the connection between the second terminal of the gating module 130 and the fourth terminal of the gating module 130. That is, in the case that the super capacitor module 120 is low in power, the power utilization module 210 of the cargo moving device may be powered by the storage battery module, so that the cargo moving device can move when the super capacitor module 120 is low in power, for example, the cargo moving device may return to a charging device for charging.
It is understood that the specific value of the preset electric quantity threshold may be determined according to practical situations, and the application is not limited thereto. In one embodiment, the preset charge threshold may be greater than zero.
In the embodiment of the present application, the super capacitor module 120 is preferentially used to supply power to the cargo moving device, so that the service life of the battery module 110 with long charging time can be reduced, and the charging times of the battery module 110 can be reduced. Because the super capacitor module 120 has the characteristic of fast charging, the power supply mode of the present application can reduce the situation that the cargo moving device is not available due to the charging of the electric energy providing module (including the super capacitor module 120 and the storage battery module 110). Meanwhile, the storage battery module 110 is used as a backup power source, so that the cargo moving device can return to the charging equipment for charging under the condition that the electric quantity of the super capacitor module 120 is exhausted, and manual intervention is not needed for charging. Therefore, under the power supply mode of this application, goods mobile device can have longer usable time, and then can improve storage efficiency.
In one embodiment, the power supply terminal of the super capacitor module 120 may be connected to the power input terminal of the power supply control module 140, so that the power supply control module 140 may be powered through the super capacitor module 120. The power input end of the power supply control module 140 refers to a terminal of the power supply control module 140 for receiving working power, and the power supply control module 140 can perform driving operation based on the power input through the power input end. Therefore, the energy storage module arranged in the power supply circuit can supply power to the power supply control module 140, and a special power supply source is not required to be additionally arranged for the power supply control module 140, so that the size and the weight of the power supply circuit can be reduced.
In one embodiment, as shown in fig. 2, the power supply terminal of the battery module 110 is connected to the power input terminal of the power supply control module 140, so that the power supply control module 140 can be supplied with power through the battery module 110. In this embodiment, the energy storage module disposed in the power supply circuit supplies power to the power supply control module 140, and a dedicated power supply does not need to be additionally disposed for the power supply control module 140, so that the volume and weight of the power supply circuit can be reduced. Meanwhile, considering that the energy density of the battery module 110 is greater and more electric energy can be reserved, when the power supply control module 140 is supplied with power through the battery module 110, the operating time of the power supply control module 140 can be increased.
In one embodiment, the Power Supply circuit may further include an Uninterruptible Power Supply (UPS) 150, wherein the UPS 150 refers to an UPS including an energy storage unit and can be used to provide Uninterrupted Power. As shown in fig. 3, the power supply terminal of the super capacitor module 120 is connected to the power input terminal of the power supply control module 140, and the super capacitor module 120 can supply power to the power supply control module 140 when the power of the super capacitor module is not exhausted. The uninterruptible power supply module 150 is connected between the power supply terminal of the battery module 110 and the power input terminal of the power supply control module 140, in other words, the battery module 110, the uninterruptible power supply module 150, and the power supply control module 140 may be connected in sequence. The uninterruptible power supply module 150 is configured to provide uninterruptible power supply for the power supply control module 140 based on the power of the storage battery module 110 when the super capacitor module 120 is exhausted.
Due to the low energy density of the super capacitor module 120, when the moving path of the cargo moving device is too long, the super capacitor module 120 cannot provide enough electric energy for the shuttle vehicle to support the shuttle vehicle to move to the charging device for charging. After the super capacitor module 120 runs out of power, in order to avoid switching the energy storage module to cause the power failure of the power supply control module 140, and then cause the problem of data loss or control imbalance, the embodiment of the present application may supply power to the power supply control module 140 through the uninterruptible power supply module 150. Under the connection relationship of this embodiment, when the super capacitor module 120 supplies power to the power supply control module 140, the uninterruptible power supply module 150 and the power supply control module 140 are also connected through a path, so that the problem of data loss or control imbalance caused by switching the energy storage modules can be avoided, and the reliability of power supply is improved.
In one embodiment, the power supply circuit further comprises a voltage detection module 160.

It can be understood that the specific constituent elements of the voltage detection module 160 and the connection relationship between the elements can be determined according to actual situations, and the application does not specifically limit this, and only needs that the voltage detection module 160 can detect the voltage.
Specifically, the voltage detection module 160 of the present application is configured to detect a voltage value of the power supply terminal of the super capacitor module 120 and output the voltage value to the power supply control module 140.

It can be understood that the specific constituent elements of the current detection module 170 and the connection relationship between the elements can be determined according to actual situations, and the current detection module 170 is not limited in this application.
